Special Containment Procedures: All contained SCP-1617 instances are to be held within Safe class storage lockers within Site-39. SCP-1617 instances require incidental cleaning once per six months to prevent further deterioration. Excessive deterioration on an instance requires restoration work to be performed as necessary; this restoration may be performed by any qualified personnel.

New instances of SCP-1617 are to be contained by Mobile Task Force Upsilon-18 ("Digital Millennium Copyright Agents") and transported to Site-39.

Description: SCP-1617 is the collective designation of various counterfeit art pieces. Approximately 96% SCP-1617 instances have been identified as duplicates of pre-20th-century paintings or sculptures; the remaining 4% are works which exhibit similar anomalous effects, but the original works and artists are not known to have existed in any form.

When a viewer observes an SCP-1617 instance and identifies it as an artwork, they will begin to experience auditory and visual hallucinations. The visual hallucinations typically involve a geometrically simple pattern being repeatedly scrolled or manipulated, while the auditory hallucinations are typically composed of synthesized musical scores, often identified as covers of songs popular during the 1980s and 1990s. All viewers will report some manner of English-language text appearing during these hallucinations. This text typically identifies the original piece's name and artist, as well as a message which purports to be from the creator of the counterfeit piece. The hallucination will cease within 20 seconds to 2 minutes, depending on the object viewed.

After these hallucinations cease, the viewer is able to observe the SCP-1617 instance with no further anomalous effects. Should the viewer cease observing an SCP-1617 instance for a period of ten minutes, returning to that instance and viewing it again will result in an identical hallucination. Different viewers observing the same object will report similar or identical hallucinations.
